Skelbo Castle is a ruined 14th century keep, located near Dornoch, Sutherland, Scotland.

[2] The castle is located at a former ferry crossing and commanded views over Loch Fleet.

[3] King Edward I of England's commissioners were awaiting the arrival of Margaret, Maid of Norway at Skelbo Castle, when they learned of her death in Orkney in September 1290, aged 7 years, whilst on her voyage from Norway to Scotland, to assume the Scottish throne.

[7] In 1529, the castle was bought by William Sutherland, 6th of Duffus who entered into a contract with John Kinnaird Of that Ilk to pay him 2300 merks by installments and for each installment he received certain lands including Skelbo to be held from the Earl of Sutherland as overlord.

Kinnaird also conveyed to him, the lands of Aberscors, Invershin and others with the whole sale and transfer of Skelbo finally taking place on 15 September 1529.
